Java Servlet MVC Auth System 🔐

📋 Overview

A robust, production-grade Authentication System built from scratch using the Model-View-Controller (MVC) architecture.

This project demonstrates a deep understanding of core Java web technologies by implementing secure login, registration, and session management without high-level frameworks like Spring Boot. It features raw JDBC connectivity, SHA-256 password hashing, and professional logging.
